PUTTYLESS SKYLIGHT.

Specification of Letters I'atent.

Application filedjlune 2, 1914. Serial No. 842,490.

To all whom it may concern:

Be it known that I, MAXWELL R. LoEoHEL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Puttyless Skylights, of which the following is a specification.

My invention relates to improvements in puttyless skylights, the object of the invention being to'provide improved means for'supporting the panes of glass, rendering them entirely water tight without the use of putty or similar material, and provide means for carrying off the water as a result .of condensation against the surface of the glass. 7

A further object is to provide improved means for holding the panes of glass, said means operating to give an elastic support, cushioning the panes" of glass and permitting expansion and contraction without any danger of breakage or leakage.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a diagrammatic plan view showing an ordinary straight skylight. Fig. 2 is a broken view in longitudinal section on an enlarged scale on the line 22 of Fig. 1. Fig. 3 is a view in cross section on an en larged scale on the line 3,3 of Flg. 1. Fig. 4 is a similar view on the line 4-4 of Fig. 1. Fig. 5 is a-view in longitudinal section on an enlarged scale illustrating a lap joint. Fig. 6 is a view similar to Fig. 4' illustrating a modification. Figs. 7 and 8 are views in plan and elevators more or less diagrammatic illustrating a! hip skylight embodying my improvements, and on Fig. 7 I indicate section lines 3-3 and 4-4 which are precisely the same as the sections above referred to in connection with Fig. 1. Fig. 9 is a view in section on an enlarged scale on the line 99 of Fig. 7, and F ig. 10

is a view similar to Figs. 4 and 6 illustrat-v ing another modification.

1 represents the outside walls or curbs of the skylight which are capped byangle bars 2 and covering plates 3, and anchoring clips 4 are provided to secure the skylight on the curb or wall. My invention is not limited tothis detail of construction. I have not attempted to illustrate any particular number of such anchor clips, but I would have it understood that I might use as many Patented Feb. 9,1915.

as desired and clampthem by bolts 5 which can be removed if desired.

The end angle bars 2 are connected by longitudinal vertically disposed bars. 6, which? to distinguish them from other bars, I shall hereinafter refer to them as filler bars. Tliese bars 6; at their ends, are se cured to the angle bars 2 in any approved manner, and are provided at intervals with cross pins 7.

\ On the bars 6 and extending throughout their length, glass supporting bars 9 are secured by rivets 10. The pins 7 support and limit the downward'movement of the supporting bars 9. These .bars 9 are formed from relatively thin metal plates, preferably of copper, bent intermediate their edges forming a longitudinal inverted U-shaped portion as shown at llfitting over the bar 6 and having its parallel members rigidly secured to the bars by means of the rivets above referred to.

The edges of the plate forming the bar,

intermediate portion perforated as shown at 17, so that the vertically screw-threaded portions 18 of T bolts 19 may project therethrough. The horizontal portions of these T-bolts are held against the upper edges of the bar 9 in any approved manner. As a simple means of connecting the parts, I have provided openings 20 in the sides of the springs 16 and filled said openings with solder as shown at 21, the solder operating to rigidly hold the parts together.

The lower portion of the spring, at both sides, is bowed outward as shown at 22 constituting cushioning surfaces againstwhich the edges of thepanes of glass 15 may bear.

This arrangement of' spring cushion for the edge of the glass allows the latter to expand The lower ends of the spring are curved outwardly as shown at 23, and confined under the cushioning portions l4 of the bar 9. Spring cap bars 24 are located above the bars 6 and 9 and have their edges curved outwardly and then inwardly forming spring contact points 25, engaging the upper faces of the panes of glass.

The intermediate portion of the cap bars is of general inverted U-shape and provided with openings 26 to receive the vertical portions '18 of the T-bolts 19, and dome nuts 27 ,are screwedonto the T bolts against the cap bar and permit the cap bar to be forced downwardly against the glass to hold the same as tightly as desired. It will thus be noted that the panes of glass 15 are supported upon cushions 14, and that their edges when the panes of glass expand, will engage cushions 22, so that the glass is supported bothvertically and horizontally by means of spring cushions. This insures a tight joint regardless of expansion and con- Y traction. Furthermore, the cushions 14 operate as bafiles to stop the water which condenses on the bottom of the glass, and compel it to enter the gutters 13. Any water which passes this point or which finds its way into the joint at other laces, will enter the gutters 12 and will be directed down the skylight into a-gutter 28 extending transversely across the skylight and supported in a bar 29 which is preferably of the general,

stepped form indi ated Where the skyli ht is made up of-several longitudinal sections of glass, it is necessary 1 to provide a joint which will properly connect them. In Fig. 2, I indicate a butt joint in which a transverse sheet 30, preferably of above referred to, that is to say, it is ro-. 13

provided with a condensation gutter 33, be-' low the uppermost pane of glass.

The skylight at the outside walls or curbs is provided with filler bars34 which support bars 35. These bars 35, on theirinner edges, are formed precisely like one half of the bar 9 vided with condensation gutters 12 an and with a cushion 14 to support the glass 15. The outer portion of the bar, however,

lies'flat against the filler bar 34 except at a point adjacent the upper edge of'the bar, where it is oif-st'as shown a t 36, and the lower edge-isb'ent around the curb as shown A spring 38, corresponding to spring 11. is

formed at its inner side precisely like the spring 11, that is to say, it is provided with a spring cushion 22 to receive the edge of the pane of glass, and its lower end 23 engages under the cushion portion of the bar '35. Spring bar 38 confines T-bolts 39, corresponding to T-bolts 17, and dome nuts 27 are employed to secure cap bars 40 in position.

The bars 40 bear against the glass 15, and at their'outer edges are curved as shown at 41 to project over the off-set portion 36 and shed the water that falls thereon.

At the upper end of the skylight, the glass l5'is supported between the cap bar 42 and a cushioning bar 43, both secured to a bar 44 on the outside of the angle bar 2 as shown. In the modification illustrated in Fig. 6, the parts are precisely like the construction indicated in Fig. 4 with the exception that the bar 45, corresponding to bar 9, is somewhat ditferently bent, at its lower ends to provide cushions 46 and gutters 47 corresponding to the cushions 14 and gutters '13 of the preferred form. The gutters 47 are formed by bending the edges of the bar or plate in the arc of a circle inwardly, and

the cushion portion 46 is formed by giving the edges of the plate or bar a convex curve 14 and gutters 13.

When my improvements are in use in connection with a, hip skylight such as shown in Figs. 7 and 8, the ridge bar is formed by a filler bar 52 having supporting bars 53 secured thereto and supporting on cushions 54, the panes of glass 15. i

A cap bar 55 is secured in any approved manner, and bears against the upper face of the panes of glass. The supporting bars 53 are interlocked at their upper edges as shown at 56, and between their upper and lower, edges are provided with laterally'oifset portions 57 to bear against the filler bar 52 and prevent any collapse of the ridge. The lower edges of the bars 53 are curved upwardly to form-the cushions 54, and also form condensation gutters 58, so that any moisture condensing-inside of the ridge will be carried o-if by these gutters. 4

With all forms of my improvements, it will be noted that the panes of glass are supported upon spring cushions, are pressed downwardly upon the cushions by spring cap bars, are permitted longitudinal expant emes a sion and contraction by reason of spring cushions, and condensation gutters are. provided so that all moisture forming. on the under surface of the glass; will be carriedto a common gutter or outlet and escape.

It will also be noted that the panes of glass are supported and rendered water 4 described Without departing from my invention, and hence I do notlimit myself to the precise details set forth, but consider myself at liberty to makesuch changes and alterations. as fairlyflfall within the spirit and scope of the'appendedclaims.

it) Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: i

1. 'llhe combination with a filler bar, a

. glasssupporting bar secured on the filler bar and having at its lower edge a laterally'projectingportion constituting a condensation gutter and a cushion, a pane of glass on said cushion,.. springs secured over the supporting bar and having a cushion in line with I p the edge of; the pane of glass, the free ends of said sprmgs inclosed within the laterally prO ecting portion of the supporting bar,
